When reviewing a case to evaluate the validity of a gram-negative pneumonia diagnosis, look for several indicators.

Q: I've noticed an increase in denials for diagnoses of gram-negative pneumonia. How can we ensure that our providers are accurately documenting the appropriate clinical indicators?
A: There are a few things that make gram-negative pneumonia a tricky diagnosis when it comes to denials.
Lack of appropriate treatment (not just on one or two broad spectrum antibiotics like Levaquin or Azithromycin) is one issue I frequently see.
Lack of clinical indicators, such as not including a chest x-ray, mention of sputum, or recent hospitalization on the patient chart is another reason.
When I review a case to evaluate the validity of a gram-negative pneumonia diagnosis, I look for the following indicators:
- Elevated temperature
- Mucopurulent sputum
- Intravenous antibiotics or chemotherapy in the last month
- Nursing home residence
- Recent acute care hospitalization within the last 90 days
- Dependence on hemodialysis and/or immunocompromised
- Radiology findings of a “patchy” infiltrate
- Sputum culture
- Elevated white blood cell count
The treatment is also an important consideration. Is more than one antibiotic being used, and do they reflect treatment of gram-negative organisms?
If several of these indicators are not present, I send a clinical validation query.
Also, if several indicators are present and the diagnosis of a simple pneumonia has been documented, I will query for the gram-negative pneumonia as it better reflects the level of care provided.
In reviewing a denial, I look to see if the auditor has mentioned a lack of documentation of the above criteria. If the clinical criteria are present and have been omitted by the auditor in their denial letter, your appeal will likely be successful.
